UNITED STATES PATENT ELERT CARROLL, 0F WEST BOYLS'ION, MASSACHUSETTS, ASSIGNDR TO MORGAN CONEIIIUZYCTIIION' COMPANY, 0F `VVOESCESTER, MASSACHUSETTS, A CORPORATION 01? MASSACHUSETTS.

Application filed December 17, 1923. Serial No. 631,169.

The present invention relates to apparatus s for handling coiled material, and in particui lar involves the provision of mechanism for automatically removing successively formed Aci coils of nished material, such as rods or the jlike, from the coil forming devices of a metal rolling mill, and tfor `transferring such coils to the coil conveying devices of saidmill. The invention resides in the combination and arrangementof `parts hereinafter set forth in detail, reference being had to the accompanying drawings, wherein Fig. 1 is atop plan view of the apparatus embodying the invention.

Fig. 2 is a view in side elevation of the apparatus shown in Fig. 1.

Fig. 3 is a transverse sectional view, on,

vrefer to l like suitable conveyor 2, the latter adapted for the flatwise passage of the coils therethrough, with said coils supported on the floor 3 of saidconveyor, and `moved along said tloorin any suitable manner, as by lugs "4:, 4, on an endless conveyor chain 5, which lugsproject upwardly through a slot in the floor 3 to engage the inner peripheries of successive, coils. By any suitable means, `wellknown yin the art, each hot finished piece emergingfrom the mill is formed iinto a coil around the upstanding guide lingers 6, 6 of the device 1, being supported duringthis operation on an apertured plate 7 through y which said lingers project; while the coil is being formed the plate 7 occupies the lower dottedlline position shown in Fig. 2, and after completion of the coil, said plate is `elevated in the usual mannerto `support the formed `coil abovethe lingers 6, 6, thus to and i transferring and supporting device 1 and a inutile or otherfacilitate its'tralnsfer to the conveying device 2, as hereinafter described.

The said conveying device 2 provides a trough-lil're extension 9, the floor 10 of which issubstantially flush with the floor 3,;Aat its end adjacent to theeoilsupporting device l., said floor 10 has pivoted thereto the wings ll, 11., whose cuter edges conform substan-` tially to the circular edge of the plate 7. ln this way, a substantially continuous plane surface is always insured for the flatwise movement of successive coils from the plate 7 to the floorof trough 9, since the wings 1l, being hinged, will invariably adjust themselves to variations in the height to which said plate is elevated. The floor 1() of trough 9 is longitudinally slotted as "at 12, for the passage of lugs 13 on a suitable endless chain 14. As shown in the drawings, the latter drives a sprocket wheel 15 on a driving shaft 16 of the mechanism, and passes around a double sprocket wheel 17, the latter being driven by the endless chain 5 of conveyor mechanism 2, which, in'turn, may be drivengby any suitable means, notshown.

For sliding each coil as formed, olf the plate 7 and across the wings ll onto the bot tom 10 of trough 9, so that it will be in a position 'tobeengaged internally by one of the lugs 13, the invention provides a `mechanical hook, operated in synchronism with the lugs 13, `and adapted to enter the opening `ofthe coil `from the top, so as not to interfere with the operation of the plate 7. This hook, designated 18, is supported at @the juncture of two converging bars 19, 19

having parallel extensions 20, 20. The bars 19, 19 are pivoted at 21, 21 to the free ends of parallel lever arms 22,22, the latter being joined for movement in unison by a cross rod 23 and beingtheinselves pivoted on the opposite sides of the trough `9 at the alined pivotal points 24;, 24.

Mot-ion is imparted to the lever arms 22, 22 `to rock them back and forth on their pivots 2d, 2d by' means of a pair of links .thanthe distance separating the pivots 2li from the points of connection of the links 25, and hence the crank arms 22 are caused to oseillate, rather than to rotate, at each revolution of the shaft 27 g 'this oscillation has an amplitude, at the free ends ot arms 22, where the bars 19, 19 are carried, of

`sutlicient extent to accomplish the 'necessary niiitted by the` pivotal connections 21, 2li for eti'ectingl these up and down movement-s,` the tree ends of the extensions 20, 20 have link connections 31,131 with the corresponding links 25,25, and it is to be noted that fthe pin and slot connections -32,32 are provided @between the links 31 and-the extensions 2O toallow ot a-certain amount ot lost niotion.

lillhen the mechanism is. at rest,'whilc a coil is being formed onthe plate 7, the position of the parts is substantially as shown'inFigs. 2 and @,the hook 18 being held alcove and atone side of the coil snpporting means so `as not to interfere with the operation ot the coil forming mechanism.

Upon completion ot the coil and simultane-` ously Withtheelevation of plate 7, a clutch, not shown, :is engagechso as to rotate the Vslia'tt`27 and crank arm 26vthrough a single revolution, and to advance the chain 14 an appropriate amount.

4 in the iirst part ot this revolution of "crank arm 26, the lever arms 22 are thrown to thelett,asshown in Fig.' 7, to dispose the hook 18 diiectly-above the completed coil, `but thisaction has very little ei'eet on the hei ght oi the hook, since the relative angular position of the pivotal point 33 on i link25 only'nndergoes a slight change.

Howeverf-astlie crank arm gasses throuofh its horizontal position and approaches vertical, as illustrated in YFigs. 8 and 9, the pivotal pointfSB risessharply, and projects the hook-18 downwardly into thefopening of the coil; as illustrated inY 9,`this low position of the hook is maintained, while at the same time it begins to travel to theright, to Y draw the 'coilfoft ot' plate 7, owingto the reversal ot direction which the arms 22 undergo. The pin and slot connection 32 pre- `:ventsthe hooktrom being litted'away from 'the coil by the link 31 as theflat-ter is'carried intoits uppermost position coincident with 'the passage o't' the crank arm 26 through the vertical plane, as `indicated in Fig. 9, `and the withdrawal movement oit the coil Ain this i the slot 12. v'llheiea-tter, the right hand movementV oit the coil is continued by enbvthe lugs 1- oi" the chain 5.

gagement of said lug with the inner peripher;7 oi' said coil, and the hook 18 at this point begins to rise, so as to clear the other side ot the coil, as illustrated in Fig. l0. poii the completion o'i the full revolution ot shaft 2i', the hook moves ifroin the position shown in Fig. lO to the position shown ia Fig. (i. and is thus in readiness .tor a repetition oi' the above described cycle of operations, as: soon as another coil has been laid on the plate 7.

` lt will be understood, ot course, that the chain 'ifi transfers each coil to the conveying inechanisin-2 in position to be acted upon lily invention, lf 1= iwnv i l; i* :luv i x "'ri cette 7 is iin icpcincii upon ic usc o tivo conveyor .chains tor moving theco1ls, .since olnf'ionslv, the chain 5 could he cxtcadcr'f laround die lsprocket wheel l5 and operated, the same as chain 1-1, in timed relaiion to the hook 18.
